Doug,
These settings work with real-time data and might be adaptable to your
scenario:
GDATTIM = f12
GLEVEL = 950
GVCORD = pres
GFUNC = thte(pres,tmpc,dwpc+2)
GDFILE = $MODEL/nam/22022512_nam212.gem+$MODEL/gfs/22022512_gfs211.gem
Sincerely,
Steve

Dear GEMPAK users,
I'm interested in creating maps of equivalent potential
temperature (THTE) using ERA5 files (from the NCAR archive) in which
fields on a given day are archived in separate grib files. I'm running
into a roadblock after creating separate GEMPAK format files of each
field and then can't figure out how to get GEMPAK to recognize TMPK
from one file and RELH from another to calculate THTE on the fly. Is
the only solution to merge separate ERA5 grib files/fields into a
single "mega" GEMPAK file?
Thank you, in advance, for any suggestions you might have on
avoiding the "mega" file!
Regards,
Doug
